Overall survival was measured from the date of randomization to the date of the participant's death.
RFS was defined as the time from the date of randomization until the date of the reappearance of high-risk disease (high-grade Ta, T1 or carcinoma in situ \[CIS\]), or death, whichever was reported first. Recurrence was assessed using cystoscopy, bladder mapping, urine cytology, and computed tomography (CT)/ magnetic resonance imaging (MRI) urogram. Participants who were recurrence-free and alive or had unknown status were censored at the last tumor assessment. The Kaplan-Meier method was used to estimate the distribution of overall RFS for each treatment group.
ORR is defined as the percentage of participants who achieved a complete response (CR), or partial response (PR) based on Response Assessment in Neuro-Oncology (RANO) criteria. According to RANO criteria whereby overall RANO response is based on both radiographic response (CR: disappearance of all target lesions; PR: sum of products of diameters \[SPD\] decreased by \>=50 percent \[%\] from baseline value) and clinical performance status with steroid dose information.
ORR is defined as the percentage of participants who achieved a CR, or PR based on RANO criteria. According to RANO criteria whereby overall RANO response is based on both radiographic response (CR: disappearance of all target lesions; PR: sum of products of diameters \[SPD\] decreased by \>=50 percent \[%\] from baseline value) and clinical performance status with steroid dose information. The core panel cohort is a subgroup of the broad panel cohort with a select panel of pre-specified FGFR markers: FGFR3 mutations (S249C;Y373C; R248C; G370C); FGFR2 mutations (C382R); FGFR3 fusions (FGFR3-TACC3); FGFR2 fusions (FGFR2-BICC1; FGFR2-TACC2).
Match rate will be calculated as the percent of eligible patients who have an actionable mutation of interest and are matched to at least one of the subprotocols, and confidence intervals will be constructed using the Wilson score interval method. Patients enrolled on or after Amendment 4 will not be included in this analysis as screening of unselected patients will no longer be conducted.

Erdafitinib is being studied in oncology for advanced malignant solid neoplasms, advanced solid tumors, urinary bladder neoplasms, urothelial cancer, and urothelial carcinoma. It is an investigational small molecule developed by Johnson & Johnson (ticker JNJ) and is currently in Phase 2 clinical development.
Erdafitinib targets fibroblast growth factor receptors FGFR1, FGFR2, FGFR3, and FGFR4. It acts as an inhibitor of these receptors, which are involved in signaling pathways that can drive tumor growth in certain cancers.
Erdafitinib is developed by Johnson & Johnson, which trades under the ticker symbol JNJ. The company is responsible for the clinical development program of this small molecule oncology candidate.
Erdafitinib is in Phase 2 clinical development. It is an investigational agent and has not been approved by the FDA for any indication. The development program includes both Phase 2 and Phase 3 trials, with a total of four studies and 1,377 participants enrolled.
Erdafitinib has been studied in several clinical trials, including NCT04172675 in non-muscle-invasive bladder cancer, NCT04083976 in advanced solid tumors with FGFR alterations, NCT03473743 in metastatic or locally advanced urothelial cancer, and NCT03390504 in advanced urothelial cancer. These trials have enrolled a total of 1,377 participants.
